Here I took the Day train from Thonburi Bangkok to the river Kwai and up to the waterfall and back!
You can get your tickets at Thonburi I would get there around 730am grab your ticket, get a coffee and catch the train. Its an entire day trip really cool experience and you come right back to Bangkok just in time for dinner.
